More organized - separate layouts for 2-way traffic and Race (clockwise). That`s for you to have easy choice from offline play with AI to quicker loading in multiplayer. For that you can extract all from "Dorifto + AI.7z" into your "..\AssettoCorsa\content\tracks\doriftomountain_0.3\". Then after confirming the new layouts working you can delete the two "***_lane.ai" files from "..\AssettoCorsa\content\tracks\doriftomountain_0.3\ai\" to have the original layout for quick loading without AI.
In "2-way" I updated the "ai_hints.ini" so the opponents drive more carefully. In "Race" the line I made is deliberately constricted to the left lane. The opponents will leave space for easy overtaking and more dynamic racing with different cars.
Pitlane now is fully functional. That means starting 2-way "Trackday" or "Weekend" with 40 cars in the pits is possible.
On the screens you see my efforts to make the materials more coherent with the background and the "Sol" dynamic weather. For that you have to place the "doriftomountain_0.3.ini" from the "Dorifto + AI.7z" into "..\AssettoCorsa\extension\config\tracks\".
